ABSTRACT:
In a recording disk apparatus, a pickup element and an electric element for at lease one of supplying an electric power to at least one of a recording disk driving motor and the pickup and processing a signal to be recorded into the recording disk and/or the signal read from the recording disk are prevented from overlapping each other as seen in a thickness direction of the recording disk to restrain a thermal conduction between the pickup element and the electric element so that a thermal conduction restraining area extending along an imaginary directional line crossing an imaginary straight line passing the pickup element and the electric element as seen in the thickness direction is formed between the pickup element and the electric element as seen in the thickness direction.
